Question

Find the range of the function for the given domain. f(x)=3x-5;{-3,0,1,5}


A.{-14,-5,-2,10}

B.{-9,0,3,15}

C.{-5,-2,-1,3}

D.{0,3,4,8}

Answer 1

@AnswerMyQuestions @iGreen.

Answer 2

the range are the y values. each coordinate is (x,y). all you need to do is thist the second number in each coordinate.

Answer 3

Range is the y-values.

Answer 4

*list

Answer 5

The points are in (x, y)

So the 2nd number is the y-value.

Examples:

(3, 6)

6 is the y-value here

Answer 6

We have to find the whole points.

Answer 7

i thinking B or A

Answer 8

plug in -3 for x in the equation and solve for f(x)

Answer 9

do the same with each x value. each answer you get will be in the range.

Answer 10

\(f(x)=3x-5\)

Plug in -3, 0, 1, and 5:

\(f(x)=3(-3)-5\)

\(f(x)=-9-5\)

\(f(x)=-14\)

So our first point is (-3, -14)

Answer 11

What's the range in (-3, -14)? @idontwantogotosleep

Answer 12

next just plug in 0. \[f(x)=3(0)-5\]

Answer 13

No, he just needs to find the range of (-3, -14) and he has his answer.

Answer 14

would A be correct /.

Answer 15

Yes!

Answer 16

(-3, -14)

The range here is -14. And only one option has -14 in it..A.
